Time for some comedy.
Monty Python are a British comedy group consisting of Graham Chapman, John Cleese, Terry Gilliam, Eric Idle, Terry Jones, and Michael Palin. Jones and Palin met as part of the Oxford Review at Oxford University. Chapman, Cleese and Idle met in the Cambridge University Footlights Review, which resulted in their touring the USA and meeting Gilliam in New York City.
The Pythons wrote and performed on various different television shows with The Frost Report being the 1st show to use the talents of all 6 members. The BBC offered Chapman and Cleese their own TV series and, after a number of chance happenings, all 6 members were again brought together to create Monty Python's Flying Circus which first aired in 1969. They produced 45 episodes over 4 seasons and made 5 feature length movies, as well as a number of albums, books, games, theatre shows and TV specials.
After the original Python series had finished the Pythons all worked on various projects, often collaborating with, or including, other members of the team. They are generally credited with reshaping British comedy and have influenced many comedians that have emerged since.
Always Look on the Bright Side of Life is the final song (as can be seen by the closing credits at the end of the clip) of the film Monty Python’s Life of Brian. Both the film and this song upset a number of Christian groups who wrongly thought that the show was parodying the Gospels and they were originally met with protests and, in some countries, complete bans.
The song was written by Eric Idle, who also sings the lead part, and is sung after Brian (played by Graham Chapman) has been sentenced to death by crucifixion and is contemplating his imminent death. Idle‘s character, who is also being crucified, on a neighbouring cross sings the song to cheer up Brian and everyone else who are also being crucified then join in the song and dance number while tied to crosses.
